I will contact the manufacturer of our tile and see what they recommend. Damn, it would be tough to do business with a company from another state. The guy today that ran the drone lives 3 or 4 blocks away. (if you know what i mean) I have already contacted local contractors about the roof and I don't even get a call back. Not interested. I have talked to 3 masons about getting the chimney flashed and tuckpointed and everybody bails out because of the clay tile. Our house was on the market for a couple years and the roof was a turn off. It scared people away. Someday within the next 15 years we will probably sell the house. (I will be 80 then) I don't want to put a ton of money in the roof and still have a house that everyone is afraid to buy. A new type roof (15 years old) with a lifetime transferable warranty is a lot easier to sell than a 120 year old roof that has been rebuilt with no warranty and everybody refuses to work on. That's my way of thinking.
